This chapter describes command-line options available in _all_
versions of the GNU assembler; *note Machine Dependencies::, for
options specific to particular machine architectures.
If you are invoking `as' via the GNU C compiler (version 2), you can
use the `-Wa' option to pass arguments through to the assembler. The
assembler arguments must be separated from each other (and the `-Wa')
by commas. For example:
gcc -c -g -O -Wa,-alh,-L file.c
This passes two options to the assembler: `-alh' (emit a listing to
standard output with high-level and assembly source) and `-L' (retain
local symbols in the symbol table).
Usually you do not need to use this `-Wa' mechanism, since many
compiler command-line options are automatically passed to the assembler
by the compiler. (You can call the GNU compiler driver with the `-v'
option to see precisely what options it passes to each compilation
pass, including the assembler.)
